Cluster:
(Earth)
The Cluster mission is comprised of four identical spacecraft launched into large, elliptical polar orbits around the Earth. After transfer to their operational orbits they will fly in formation to allow scientists to measure subtle changes in the interaction between the Earth and the Sun. The four spacecraft will look at how particles from the Sun interact with the Earth's magnetic field. Cluster will observe the magnetic and electrical interactions between the Earth and the Sun, by making direct measurements of the fields and particles trapped in the Earth's magnetic field. For the first time, small-scale fluctuations in interplanetary space will be measured between each spacecraft as they orbit the Earth.
